Well, that's not a QB program... it was a demo-thing that rattra made in FB. Lut's do still speed programs up though, even in C/C++. I mean, if you had a really old QB program, probably something that was coded before 1990, you would different kinds of lut's to make it run faster. Such as a lut to calculate the pixel position in a buffer when it only requires integer mul's to calculate. That would be a waste, and maybe even slower to look up. With the trig functions though... I haven't seen a program yet that doesn't run faster by looking those up.
